Fast Radio Bursts and Interstellar Objects [PDF]
The Astrophysical JournalFast radio bursts (FRBs) are transient radio events with millisecond-scale durations and debated origins. Collisions between planetesimals and neutron stars (NSs) have been proposed as a mechanism to produce FRBs; the planetesimal strength, size, and ...

Interstellar Objects Follow the Collapse of Molecular Clouds [PDF]
The Astrophysical Journal, 2021 Abstract Interstellar objects (ISOs), the parent population of 1i/‘Oumuamua and 2i/Borisov, are abundant in the interstellar medium of the Milky Way. This means that the interstellar medium, including molecular-cloud regions, has three components: gas, dust, and ISOs.

Capture of interstellar objects – II. By the Solar system [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Capture of interstellar objects (ISOs) into the Solar system is dominated by ISOs with asymptotic incoming speeds $v_\infty \lt 4\,$km s−1. The capture rate is proportional to the ISO phase-space density in the Solar vicinity and does not vary along the Sun’s Galactic orbit, i.e.

Close encounters of the interstellar kind: exploring the capture of interstellar objects in near-Earth orbit [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Recent observations and detections of interstellar objects (ISOs) passing through the Solar system have sparked a wave of interest into these objects. Although rare, these ISOs can be captured into bound orbits around the Sun. In this study, we investigate the novel idea of capture of ISOs into near-Earth orbits and find that a ...

The Distribution of Earth-impacting Interstellar Objects
The Astrophysical JournalIn this paper we calculate the expected orbital elements, radiants, and velocities of Earth-impacting interstellar objects. We generate a synthetic population of ∼10 ^10 interstellar objects with M-star kinematics in order to obtain ∼10 ^4 Earth ...

Interstellar Objects in the Solar System [PDF]
1I/`Oumuamua and 2I/Borisov are the first macroscopic interstellar objects to be detected in the solar system. Their discovery has triggered a tsunami of scientific interest regarding the physical properties, dynamics and origin of the so-called interstellar interloper population.

Capture of interstellar objects – I. The capture cross-section [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We study the capture of interstellar objects (ISOs) by a planet–star binary with mass ratio q ≪ 1, semimajor axis ap, orbital speed vc, and eccentricity ep. Very close (slingshot) and wide encounters with the planet are amenable to analytical treatment, while numerically obtained capture cross-sections σ closely follow the ...

Interstellar Extinction from Large Surveys [PDF]
Open Astronomy, 2003 Under some assumptions, information on interstellar extinction may be obtained from modern large photometric survey data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys.
